What applications are brushless DC motors suitable for?

1. In electronic devices and instruments
Due to the needs of surgery, medical devices require their power system to continuously change speed over a wide range to meet the requirements of various occasions such as milling, drilling, and sawing. Due to the presence of electric brushes and phase converters, disinfection is not possible before surgery, which has a certain impact on the effectiveness of the surgery; Regular replacement of brushes and motor maintenance are required.
After using brushless DC motor as the driving system, it has advantages such as low noise, wide range speed regulation, small size, and light weight. In addition, applications in computer hardware, floppy disk drives, drum drives, laser printer monitoring equipment, and other fields are gradually replacing brushless motors. This type of DC brushless motor has a small size and high processing accuracy, and belongs to the technology intensive category, with a huge demand.

2. Industrial automation equipment field
The advantage of using a DC brushless motor in industrial sewing machines is that it can achieve forward and reverse rotation, as well as automatic sewing and cutting, fast starting and braking, high positioning accuracy, and large overload capacity.
In addition, the use of brushless DC motors in CNC machining equipment can meet the requirements of high precision, efficiency, and performance of mechanical equipment. Many light industrial machinery that require accurate control of speed and position also use DC brushless motors.

3. In electric bicycles
The DC brushless motor used in electric bicycles is usually made into a disc motor, installed in the wheel hub, which is connected to the rim by spokes and directly drives the wheel to rotate. The stator is composed of stator core, armature winding and its lead wire, sensing element and its lead wire, stator bracket, shaft, and other parts.

The stator core is generally made into multiple pairs of poles with multiple slots to meet the requirements of high torque and low speed. The form of stator winding is similar to that of multiphase permanent magnet synchronous motors, and it plays an important role in achieving energy conversion.
